The lady selling these is legit, but should sharpen her eBay skills a little. Making threats is not the best way to sell something. Her prices have been all over the place with these. The market is not like it used to be for these anymore IMO. Real casino chips come to the market now, back then, not so much.
I am selling 20 of the rare and highly valuable Paulson vineyard casino $500 poker chips. They are valued at $300 per chip..these are the last of the $500 chips that I will be selling forever, you will never see them being sold for a price like this again so get them while you can because its your only and last chance
